WHAT WAS THAT DEMENTED HOWL?

As you move along the tunnel's interior, you hear screeches and howls that could only come from the nastiest of creatures. Just hope you don't meet any of these creatures during your escape. You give a sigh of relief that you brought your Indiglo watch and your glow-in-the-dark trout to school with you. He's the only thing providing any visibility in this dismal cavern.

Your trout shows that you have reached another large underground room. And, of course, there are three passable tunnels beckoning you from the other side. You ponder for a moment, but then head into:

The tunnel on the left, which is easily tall enough for you, but smells a bit like week-old garbage?
The center tunnel, in which you'd have to crouch down, but it doesn't smell so bad?
or The tunnel on the right, which looks to be a tight fit?

Make your selection, and hope it's a good one, because your trout won't last all day!
